Same for me but I managed to rescue the existing installation, but unfortunately my reverse proxy for the web interface doesn’t work anymore.

I’m using shelly sensors which work well with HA

yes, you should definitely check regularly if the Automation does what you want, there are some stumbling blocks e.g. Difference of presence detection and persons. I spent about a month until I’ve understand enough so that it does what I want :)

That’s exactly how I do it too, I think otherwise this automation would be too complex to handle (it is already very complex) 😊
